TriQuint launches high-performance filters for LTE

RF front-end component maker and foundry services provider TriQuint Semiconductor Inc of Hillsboro, OR, USA has announced several new premium filters for next-generation smartphones and other mobile devices. The high-performance filters use the firm’s acoustic wave filtering technologies to address what are described as some of the industry’s toughest LTE interference problems.

The number of cellular and Wi-Fi bands packed inside compact high-end smartphones is rocketing to support 2G/3G/4G voice and data services, as well as global roaming, says TriQuint. Advanced filter technology is required to mitigate the resulting interference issues. A global spectrum crunch adds to the growing interference problems as governments around the world squeeze new 4G bands with higher performance requirements next to existing bands, often with minimal band guards, the firm adds.

TriQuint says that its specialty filters are capturing numerous design wins in high-volume 4G smartphones from multiple manufacturers, as well as sockets on reference designs from leading chipset suppliers.

The new filters include what is claimed to be the industry’s first diplexer for LTE Bands 38 and 40 (the 1.7mm x 1.3mm 885043), which is more than 30% smaller than discrete solutions. The firm has also unveiled the first carrier aggregation module for Bands 2/25 and 4 (the 3.6mm x 2.0m TQQ2504), an integrated quadplexer that is half the size of discrete architectures. TriQuint’s new Band 7 LTE duplexer (the 2.0mm x 1.6mm TQM976027) and its Band 41 LTE receive filter (the 2.0mm x 2.0mm TQQ0041) both achieve low insertion loss to help maximize the incoming signal strength, resulting in higher data throughput over longer operating distances.

TriQuint is exhibiting the new devices at the Mobile World Congress 2014 in Barcelona, Spain (24-27 February).
